Chapter 24 | The Case of One Who Experiences a Wet-Dream During the Night in the Month of Ramadan or at Other Times and Does Not Shower before Dawn or It Occurs During the Night or Day
3ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ فَضَّالٍ عَنِ ابْنِ بُكَيْرٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) عَنِ الرَّجُلِ يُجْنِبُ ثُمَّ يَنَامُ حَتَّى يُصْبِحَ أَ يَصُومُ ذَلِكَ الْيَوْمَ تَطَوُّعاً فَقَالَ أَ لَيْسَ هُوَ بِالْخِيَارِ مَا بَيْنَهُ وَبَيْنَ نِصْفِ النَّهَارِ قَالَ وَسَأَلْتُهُ عَنِ الرَّجُلِ يَحْتَلِمُ بِالنَّهَارِ فِي شَهْرِ رَمَضَانَ يُتِمُّ صَوْمَهُ كَمَا هُوَ فَقَالَ لا بَأْسَ.
3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from ibn Bukayr who has said the following: “I once asked abu ‘Abd Allah , about a man who experiences sexual relation (because of which Ghusl (bath) is obligatory); then goes to sleep until the morning, if he can fast that day an optional fast. He (the Imam) said, ‘Up till midday it is up to his choosing.’ I then asked about a man who experiences wet dream during the day in the month of Ramadan; if he completes his fast as it is. He (the Imam) said, ‘It (completing) is not harmful.’”
